PPS 15: Planning and Flood Risk
The Role of Development Plans: Achieving Sustainable Patterns of Development
6.2 To assist in meeting the sustainability objectives of the Regional Development Strategy and the Northern Ireland Sustainable Development Strategy new development proposals brought forward through the development plan process should be in harmony with the water environment and avoid working against it.
6.3 The strategic flood risk information and advice provided by the Rivers Agency at development plan preparation stage will take account of climate change which is expected to worsen future flooding. Development plans will therefore adopt a precautionary approach to development in areas that may be subject to flood risk.
6.4 Consequently development plans will not bring forward sites or zone land that may be susceptible to flooding, now or in the future, unless the most exceptional circumstances exist. Where, exceptionally, a plan brings forward such a site, it will explain the reasons why it has done so and set out the measures necessary to mitigate the risk.
6.5 As part of a precautionary approach, development plans will also need to examine the potential to remove undeveloped areas which are, or may be at future risk of flooding from within settlement limits where it is appropriate to do so, for example at the fringe of towns or villages.
